Doctrinal reversal High confidence 12 rulings · 2015–2025

Current position

Amounts resulting from the mutual agreement termination of an employment relationship are considered income obtained in a notoriously irregular manner. To apply the 30% reduction under Article 18.2 of Law 35/2006 on Personal Income Tax (IRPF), the compensation must be attributed to a single tax period. This reduction is subject to an annual limit of 300,000 euros.

The DGT has moved from denying the reduction on gratifications from collective agreements—on the grounds that they did not fit the Regulations or lacked a generation period exceeding two years—to recognizing the irregularity in compensations for the suppression of supplements or pensions. Currently, the criterion extends to amounts resulting from the mutual agreement termination of the employment relationship.

  1. V1132-20

  2. V2368-25
